UNITED STATES PATENT OFFICE- EDWARD :o. THAYEB, or WORCESTER, MASSACHUSETTS,- ASSIGNOR, BY MESNE ASSIGNMENTS, TO OROMPTONE: KNOWLES LOOM WORKS, A CORPORATION OF MASSACHUSETTS.

FILLING-DETECTOR son. Looms.

Application filed July 12, 1906. Serial 1Y0. 325,803.

To all whom it may concern:

Be it known that I, EDWARD D. THAYER, a citizen of the United States, residing at- VVorcester, inthe county of Worcester and State of Massachusetts, have invented a new and useful Filling-Detector for Looms, of which the following is a specification.

This invention relates to a mechanism for Y measuring the filling on a bobbin in the shuttle of aloom and for calling a shuttle changing mechanism into operation upon the exhaustion of the fil]1ing. u

,The device consists'of a detector or feeler arranged in position to press on the filling thus allow the feeler to act. Upon the exhaustion of the filling on the bobbin in the shuttle, the lever w1ll come into position to actuate connections which extend to a shuttle changing mechanism. 'In this way,

a simple and accurately operating detecting mechanism is provided.

The device is illustrated in the accom- 85 panying drawing, referring to which,

Figure 1 is afront elevation of the end of, a lay and shuttle-box with my improvement applied thereto. Fig. 2 is a partial end elevation on a red-ucedscale showing the operating connections. Fig. 3 is a partial' detail perspective view of one end of the operating lever. Fig. 4 is a partial sectional View ofthe end of the shuttle showing the detector, and Fig. 5 is a detail view of the detector.

Referring to the drawing and in detail, A 3

designateathe lay, B the shuttle box, G the picker-stick, D the shuttle, and E the spring binder which holds the shuttle in the box. These parts may be of any ordinary or approved construction.

A lever 11' is pivoted to the. under side of the shuttle box. This'leverhas 'a projection l0.which rides on 9. stations cam 12 as the-lay beats back'and forth. on

the lay beats up, the projection 10 will surface. is arranged substantially concentric with the travel 'of-the lay so that there will be practically no motion of the lever, but as the lay continues its movement, the projection 10 will run down the incline 121 and lever 11, as shown in Fig. ,1, to drop. A

spring 122 is arranged between the shuttle box and the lever so as normally toforce the projection 10 to engage the cam 12. A stud,

13 is adjustably secured in the other end of the lever'll. This stud is arranged in position to engage a feeler or detector 14 arranged in the shuttle D in position to bear on the filling .F, wound on the bobbin G in the shuttle. This detector consists of a hold the lever 11, as shown in Fig. 1. -That is,"as the projection 10' starts to run down the incline 121, the same will be prevented from dropping by the engagement of the stud 13 with the feeler or detector which, if

there is yarn on the bobbin, prevents the leve'r ll-from dropping." When the filling becomes exhausted on the bobbln, however,

the lever will drop as the lay beats upand the end of the same willengage and push on a rod 15 which engages a lever 150 secured on a rock-shaft 16 which extends'into posi- Specification of Letters Patent. I I Patented Feb, 20, 1912.

travel on the part 120 of the cam 12, which i this will allow the right-hand end of-the spring arm 14 and .face or bearing piece 140. When the bobbin is full, the detector will tion and which controls the shuttle changing mechanism.

Attached to the binder E ,is'a locking arm 17 which extends in position to come under the right-hand end of the lever 11. When there 'is no shuttle in the shuttle box, the arm 17 will hold the lever from operating,

but when the shuttle comes into the box,-the

"binder will be pushed out-and the lower hooked end 170 of the locking arm "17 will be moved out clear of the operatinglever;

11. By this arrangement, the detecting, mechanism can only act when thereistashuttle in the shuttle box.

"By this arrangemenna sim. re and ef fective mechanism '15 rovlded or the purpose stated, which mec 'anism is'very smooth.

and easy in action. A

The details and arrangements. herein shown and described maybe greatly varied by e. skilled "mechanic without departin from the scope of my invention as exprem in the claims. I

Having thus fully described my invention,

what I claim and desiretd secure by'Le-tters-Patent is 1. Ina device of the character described,

the combination of the lay carrying a shuttle box, a filling detecting mechanism arranged in'connection with the shuttlebox, means separatefrom the filling detecting, mechaa nism for holding the filling detecting mechanism out of operation until a shuttle comesinto the box, said means being located in osition to be engaged by the shuttle when -1't comesinto the box, and a shuttle adapted to render the filling detecting mechanism shuttle box, a binder for holding the shuttle operative by engaging said means.

2-. In a device of the character described, the combination of a shuttle box, a filling detecting mechanism arranged in connection therewith, a lock for holding the filling de- .tecting mechanism inoperative, a shuttle,

and means whereby the lock Will be released when'a shuttle comes into the shuttle box.

I 3. In a device of the character described, the combination of "the .lay carrying the in the-box, a filling detecting mechanism arranged in connection with the-box, ad a lock actuated by the binder for holding the detecting mechanism inoperative until a shuttle comes into the box;

4. In .a filling detecting mechanism, the combination, of a lay, a shuttle box, a lever pivoted thereto, ,a stationary cam which 'said lever engages, a feeler mechanism arranged in connection with said lever toengage the filling on the bobbin in the shuttle,

operating connections arranged in the path said lever, and means'for holding the lever out of operation until 'a' shuttle comes the filling on the bobbin, a pivoted lever having a projection to engage said feeler, a stationary cam whereby said lever will be v1- brated as the lay beats, connections arranged in the path of-said lever to be foperated upon the exhaustion of the filling, and meansfor locking the lever in inoperative position until a shuttle comes into the box 6. In a filling "detecting mechamsm, the combination of alay, a shuttle box, a binder for holding the shuttle in the box, a shuttle, a feeler arranged in the shuttle to engage the fillingon the bob-bin, a spring-pressed pivoted lever arranged in position to engage the feeler, a stationary cam for causing said lever .to vibrate as the lay beats, connections arranged in the path ofsaid lever to be struck by the same upon the exhaustion of the filling, and a lock extending from said binder to engage said lever and hold the same inoperative until a shuttle comes into said shuttle box. p y

In testimony whereof I have hereunto set myhand, in the presence of two subscribing witnesses.
